T '0 all whom it concern: p

, Be it. known that I, LOUIS P. TosADoRI, a

citizen of the United States, residing at Beaver, F alls county of Beaver, and State 5 of Pennsylvania, have invented a new and usefulv Improvement in Apparatus for P e paring Skins for Stitching, of. which the following is a full, clear, and exact idescrip-i tion. I

The present invention relates to an apparatus for rece ving, preparing and holding sections ofgut or skins, such as used for the production of sausages of. certain kinds, for stltchmg. v

5 Infthe production of sausages of certain kinds, it is very desirable to form gut casings which are much larger-than can be procuredinatural-ly; Fr th1s purpose, 1t is cusi tomary to take twoor more sections of gut and stitch the same, whereby the diameter ofthe casing so formed will be. substantially eqlualqto the total diameters of the two.

smallest sections employed. I It is the-object of thepresent nvention toprovi-dea portable apparatus-adapted to,

receive; and prepare sections of gut of this character"forstitching., I I

. In the accompanying. drawings, I have shown, for purposes of illustration only, a

preferred embodiment of the present invention,,in-which: p v 7 3 Figure 1 is a top plan view of the gut receiving mandrel having the locking strips in position thereon,

Figure 2 is a side elevation, on an enlarged scale, of a portion of the gut receiving end of the mandrel illustrated in Figure 1, I

Figure 3 is a transverse sectional view on the line IIIIII of Figure 1, t

Figure 4 is a side elevation of one of the clamp-ing strips,

Figure 5 is a transverse sectional view on the line. V V of Figure. 4,

5 Figure 6 is a transverse sectional view through the mandrel illustrating two sections of gut inrposition thereon,

Figure 7 is a view corresponding to Figure 6 illustrating the gut sections as severed,

' and there is provided a mandrel 2 which may be than the normal 6 to 8, both inclusive, holding the clamping formediofiany desiredmatelrial and ofany I both of the strips being of similar construction. Preferably the stripsare formed with a pair, of side channels 7 separated by an, intermediate ridge 8. The channels are. of a suilicient depth to receive therein, longitudinally extending lock-ing wires9. At spaced points throughout their lengths, the locking wires, which may be formed of any desired resilient material, are secured to the body of the locking strips by spots of solder 10. Intermediate the points of attachment of the locking wires, the bodies'of the locking strips. are formed with a plurality of openingsll having a diameter which is slightly greater Wires. I

Adapted to; cooperate with. the locking strips is a pair of separable clamping strips 12. Each clamping strip has projecting therefrom at intervals corresponding tothe distances between the openings 11 perfo-rating and clamping pins 13. These pins are distance between the locking 1 each provided on opposite sides thereof 7 with grooves 14 adapted to receive the locking wires 9 when the clamping strips are forced into position, as indicated in Figures and thereby firmly strips and locking strips together.

In the use of the-apparatus, the locking strips vare inserted in position in the channels in a mandrel 2, as indicated in Figure 1. Thereafter, any desired number of gut sec tions 15 is slipped over the end ofthe mandrel. After the desired number of gutsections is in position, there is applied a holding clamp 16 having aportion 17 adapted to enter an opening 18 in the endof the mandrel, and a second portion 19 adapted to pass through the portion of the gut sections between the locking strips 6 into engagement with an opening 20 in the body of the mandrel. This clamp holds the skins or gut sections against longitudinal movement on the mandrel, and thereafter they may be stretched and smoothed on the mandrel as required. Afterthe smoothing operation, the gut sections are clamped in position by applying the clamping stripsl2, and forcing the pins 13 between the locking wires 9. This spreads the locking WllGSLlIltll such time as the pins 13 have passed through the openings 11' and into the pockets 2lprovided therefor in the body of the mandrel. Thereafter, the wires spring into engagement with the grooves 14 and hold the clamping bars in position. i

The gut sections at this time occupy substantially the position indicated in Figure 6. They are then severed intermediate the respective strips in any desired manner, as indicated in Figure 7. Thereafter, each locking strip With its cooperating clamping strip is bodily removed from the mandrel and the parts may then be relatively separated, as indicated in Figure 8. At this time, the gut sections may be fed to a stitching machine, which stitches the same along the lines 22 indicated in Figure 8. The respective strips are then separated to release the gut, and the casing is then turned inside-out tobring the severed edges 23 on the inside, and provide a smooth exterior.

The advantages of the present invention arise from the provision of an apparatus of this character enabling gut sections to be easily prepared for stitching, and for effectively clamping the severed edges during the stitiching operation, the entire apparatus being portable and composed entirely of relatively separable or movable parts, permitting the same to be'easily cleaned and assembled.

I claim:

1. In a gut holding apparatus, a mandrel having a channel therein, upwardly projecting pins in said channel, a pair of separable locking strips remova-bly held in position by said pins, and a pair of separable clamping locking stripsremovably held in position,

in said channel, each of said locking strips having a plurality of openings formed therein and having locking Wires extending longitudinally of the strip and lying on opposite sides of said openings, and a pair of separable clamping strips adapted to co operate with said locking strips, said clamping strips having pins adapted to extend between said locking'wires and through said openings for clamping gut sections in position, each clamping strip and its'coo-perating locking strip being bodily movable relative to the other clamplng strip and its cooperating locking strip to separate the severed edges of the gut section preparatory to,

stitching, substantially as described.

In testimony Where-of Ihave hereunto set my hand.
